In this article, let us review the Linux file-system structures and understand the meaning of individual high-level directories. 1. / – Root Every single file and directory starts from the root directory.

  We're platform agnostic at Lifehacker, which is why we love dual- and triple-booting our computers. Unfortunately sharing data between operating systems can be a huge headache. Here's how to stay organized by keeping it all in one place. There's nothing more annoying than booting into OS X only to realize you need access to some files on your un-readable Linux partition; or Windows; or any combination thereof.
